Air India dispatch error forces 14‑hour 'flight to nowhere' after leased 777‑200LR sent to Vancouver
Air India dispatched a leased, ex‑Delta Boeing 777‑200LR instead of the intended 777‑300ER on a Delhi–Vancouver service, leaving the aircraft without required emergency-oxygen configuration/Canadian clearance for the terrain‑critical routing. Flight AI185 returned to Delhi mid‑flight after nine hours airborne, burning fuel and stranding passengers.
